NXP Semiconductors NVT4858-4557-EVB Level Shifter Evaluation Board

NXP Semiconductors NVT4858-4557-EVB SD/SIM Level Shifter Evaluation Board includes a mounted NVT4858/NVT4557, input and output headers, with one SD card socket and one SIM card socket. There are four 100 mil headers, and the connections to all of the pins of the NVT4858 and the NVT4557 are available at these headers. The SIM card or the SD card that is inserted in the socket can be directly accessed by the SD host controller or the SIM controller via the 100mil headers on the host interface side of the level shifter.

The easy-to-use NXP NVT4858-4557-EVB evaluation board is designed to be a stand-alone board allowing the performance of the NVT4858 or the NVT4557 to be evaluated.
